Actually, I'm pretty sure it's the one he loved telling him that she will survive, and carry on his memory. I think if you look at the album as a whole, and as a story where he is dying, he dies in Disenchanted (when it gets quieter and quieter, at the end of the song). Then this follows and this is the girl speaking. My friend and I (yes we may be losers), we spent hours going over this album, and that's what we concluded.
